The invention provides a secondary platform dynamic leveling system and belongs to the technical field of platform dynamic leveling. The drive output shaft of a first motor driver, the drive output end of a second motor driver and the drive output end of a third motor driver of an industrial personal computer assembly are connected with the coil input end of a voice coil motor rotor of a first belt gas cylinder, the coil input end of a voice coil motor rotor of a second belt gas cylinder and the coil input end of a voice coil motor rotor of a third belt gas cylinder respectively. The drive output ends of a first proportional electromagnetic valve, a second proportional electromagnetic valve and a third proportional electromagnetic valve of the industrial personal computer assembly are connected with the input end of an electronic control proportional pressure-adjusting valve of a voice coil motor of the first belt gas cylinder, the input end of an electronic control proportional pressure-adjusting valve of a voice coil motor of the belt second gas cylinder and the input end of an electronic control proportional pressure-adjusting valve of a voice coil motor of the third belt gas cylinder respectively. The secondary platform dynamic leveling system is good in instantaneity in the dynamic leveling process, the inclination conditions of a platform can be accurately detected, and then leveling is quickly performed. Leveling precision is high and can reach the arc second grade.
Description
technical field [0001] The invention belongs to the technical field of platform dynamic leveling. Background technique [0002] In modern society, a high-planarity platform is often required. For example, in full-physical simulation experiments such as space intersection and docking, ground measurement, navigation, network communication, and formation control, it is necessary to support the entire ground simulator and provide a basic platform for ground simulation experiments. ; Provide platform support for physical simulation tests such as formation satellite ground test verification and control algorithm verification analysis. Since the platform may be in a tilted state due to the unevenness of the large-area horizontal base when it is moving or stationary, it is not conducive to providing a working platform as horizontal as possible for the load to ensure accurate docking. Be quickly and accurately leveled to ensure sufficient levelness of the platform. [0003] The cor...
